It consists of copper(II) bonded to carbonate and hydroxide with formula Cu 2 (CO 3)(OH) 2. It is a green solid that occurs in nature as the mineral malachite . It has been used since antiquity as a pigment , and it is still used as such in artist paints, sometimes called verditer , green bice , or mountain green .
Copper(II) carbonate or cupric carbonate is a chemical compound with formula CuCO 3. At ambient temperatures, it is an ionic solid (a salt) consisting of copper(II) cations Cu 2+ and carbonate anions CO 2− 3. This compound is rarely encountered because it is difficult to prepare [2] and readily reacts with
relative molecular mass: M r: Ratio of the average mass per molecule or specified entity of a substance to 1/12 of the mass of an atom of the nuclide 12 C number of molecules or other elementary entities: N: Number of molecules or other elementary entities in a system: one: 1: amount of substance: n, (ν) mole: mol
The molar mass of atoms of an element is given by the relative atomic mass of the element multiplied by the molar mass constant, M u ≈ 1.000 000 × 10 −3 kg/mol ≈ 1 g/mol. For normal samples from Earth with typical isotope composition, the atomic weight can be approximated by the standard atomic weight [ 2 ] or the conventional atomic weight.
Mole ratio: Convert moles of Cu to moles of Ag produced; Mole to mass: Convert moles of Ag to grams of Ag produced; The complete balanced equation would be: Cu + 2 AgNO 3 → Cu(NO 3) 2 + 2 Ag. For the mass to mole step, the mass of copper (16.00 g) would be converted to moles of copper by dividing the mass of copper by its molar mass: 63.55 g/mol.
